Someone suggested on the LF forum, that one could make one's own ground glass--chemical grinding & or frosted spray. Another suggested a reputable company who does such work--Maxwell for example. Others? Another individual suggested using a computer screen, monitor screen.
Regarding this last option, a monitor screen cut to size. My question is: what pitfalls are there in using a monitor screen as a substitute for a ground glass? I have such on hand.
Another question: I have need of a ground glass screen for an unusual sized old antique camera---specifically a 6.5 x 8.5. My needs are not for a high end GG but something basic, either cut corners or sq, fresnel or not.
Since there are many options for purchase on EBay---low & high price wise, etc etc etc, would one have a suggestion regarding the purchase of an 8x10 GG and my cutting the GG down to the above size (I do have the equipment.)
Thank you for your input
